Why would they? It's absolutely different than HT. And for the user, we won't really see the benefits/negatives outright. To us it is simply a 4/6/8 core CPU, that's what the OS sees and that's what we can use.

Modules don't share anything amongst themselves, cores do.

The term module has nothing to do with Intel's Hyper Threading, or Hyper Threading in general.

Hyper Threading is Intel's version of one core acting as multiple, but it's code based as where AMD cores within a module is a physical take on the same concept instead of code based with there being individual pipelines inside the mods.

One is hardware, the other is software - that right there should tell you they are completetly different things. In addition, with BD a 4/6/8 core cpu will have just that many threads, 4/6/8. HT introduces an "extra thread" for each core. They are completely different.

As you say, HT is "Intel's version of 1 core acting as multiple" - in no way does a BD core "act as multiple cores/threads".

And PLEASE, use the edit button!

I wouldn't even try to compare it Hyper-Threading, as I don't think they are related in any way.

It's the same concept though, cause the AMD cores aren't really cores they're pipelines with a module. Kinda like multiple threads through one intel core. AMD has even stated that it's thier hardware version of hyper threading.

Wow that's a stretch... I would never consider the "Module" design to resemble Hyper Threading in any way, since the scheduler is lining up jobs for the core (or pipeline if you want to call it that) and there is one scheduler per core. Meanwhile, Hyper Threading is lining up 2 jobs for a single core in case one stalls.

Ok the way I'm looking at it is that the Intel Core = AMD Module. The pipelines aren't cores. The module is the core an its broken up into individual pipelines.

The pipelines make up the cores. There are 2 integer "cores" per "module." They've said this multiple times, the module is not considered a core.

Each module can process two integer threads, and two 128-bit FP threads at a time. Therefore, there are two integer "cores," and two 128-bit floating point "cores."

The number of pipelines per core may be less or more than average, but it is a core nonetheless.
